Agriculture is highly exposed to climate change, as farming activities directly depend on climatic conditions. Agriculture also contributes to climate change through the release of greenhouse gases into the atmosphere. Two powerful greenhouse gases are by-products of agricultural activity:
Methan...e (CH4) – from livestock digestion processes and stored animal manure;
Nitrous oxide (N2O) – from organic and mineral nitrogen fertilisers.
However, agriculture can also contribute to climate change mitigation by reducing greenhouse gas emissions and by sequestering carbon while maintaining food production.

Current evidence that the climate is changing is overwhelming. Impacts of climate change and variability are being observed: more intense heat-waves, fires and floods; and increased prevalence of food- water- and vector-borne diseases. Climate change will put pressure on environmental and health det...erminants, such as food safety, air pollution and water quantity and quality. A climate-resilient future depends fundamentally on reducing greenhouse gas emissions. Limiting warming to below 2 °C requires transformational technological, institutional, political and behavioural changes: the foundations for this are laid out in the Paris Agreement of December 2015. The health sector can lead by example, shifting to environmentally friendly practices and minimizing its carbon emissions. A climate-resilient future will increasingly depend on managing and reducing climate change risks to protect health. In the near term, this can be enhanced by including climate change in national health programming and creating climate-resilient health systems.

The arrival and rapid spread of the mosquito-borne viral disease Chikungunya across the Americas is one of the most significant public health developments of recent years, preceding and mirroring the subsequent spread of Zika. Globalization in trade and travel can lead to the importation of these vi...ruses, but climatic conditions strongly affect the efficiency of transmission in local settings. In order to direct preparedness for future outbreaks, it is necessary to anticipate global regions that could become suitable for Chikungunya transmission. Here, we present global correlative niche models for autochthonous Chikungunya transmission. These models were used as the basis for projections under the representative concentration pathway (RCP) 4.5 and 8.5 climate change scenarios. In a further step, hazard maps, which account for population densities, were produced. The baseline models successfully delineate current areas of active Chikungunya transmission. Projections under the RCP 4.5 and 8.5 scenarios suggest the likelihood of expansion of transmission-suitable areas in many parts of the world, including China, sub-Saharan Africa, South America, the United States and continental Europe. The models presented here can be used to inform public health preparedness planning in a highly interconnected world.

Compared with other health areas, the mental health impacts of climate change have received less research attention. The literature on climate change and mental health is growing rapidly but is characterised by several limitations and research gaps. In a field where the need for designing evidence-b...ased adaptation strategies is urgent, and research gaps are vast, implementing a broad, all-encompassing research agenda will require some strategic focus.

The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. The IPCC prepares comprehensive Assessment Reports about the state of scientific, technical and socio-economic knowledge on climate change, its impacts and future risk...s, and options for reducing the rate at which climate change is taking place. It also produces Special Reports on topics agreed to by its member governments, as well as Methodology Reports that provide guidelines for the preparation of greenhouse gas inventories.

Climate change is increasing risks to human health and to the health systems that seek to protect the safety and well-being of populations. Health authorities require information about current associatio...ns between health outcomes and weather or climate, vulnerable populations, projections of future risks and adaptation opportunities in order to reduce exposures, empower individuals to take needed protective actions and build climate-resilient health systems. An increasing number of health authorities from local to national levels seek this information by conducting climate change and health vulnerability and adaptation assessments. While assessments can provide valuable information to plan for climate change impacts, the results of many studies are not helping to build the global evidence-base of knowledge in this area. They are also often not integrated into adaptation decision making, sometimes because the health sector is not involved in climate change policy making processes at the national level. Significant barriers related to data accessibility, a limited number of climate and health models, uncertainty in climate projections, and a lack of funding and expertise, particularly in developing countries, challenge health authority efforts to conduct rigorous assessments and apply the findings. This paper examines the evolution of climate change and health vulnerability and adaptation assessments, including guidance developed for such projects, the number of assessments that have been conducted globally and implementation of the findings to support health adaptation action. Greater capacity building that facilitates assessments from local to national scales will support collaborative efforts to protect health from current climate hazards and future climate change. Health sector officials will benefit from additional resources and partnership opportunities to ensure that evidence about climate change impacts on health is effectively translated into needed actions to build health resilience.

We need to be concerned about mental health in the context of climate change
This infographic looks at how climate change directly and indirectly impacts maternal health, making pregnancy less safe and worsening neonatal health outcomes.
Health systems strengthening, including for sexual and reproductive health and rights services
Climate hazards, including extreme heat, are associated with increased risks of developing complications that lead to adverse maternal and perinatal outcomes. These may include multiple causes of maternal and neonatal morbidity and mortality such as gestational diabetes, hyper tensive disorders of p...regnancy, preterm birth, low birth weight and stillbirth. In addition to the health risks related to poor nutrition, water, hygiene and sanitation, the effects of exposure to climate hazards and their aftermath during and after pregnancy can affect mental health and contribute to intergenerational trauma. They may increase stress, anxiety and depression – known risk factors for adverse perinatal outcomes.
